That QR code may disappear suddenly? Correct way to make it to prevent "expiration" and utilization techniques

Tragedy that QR code of business card or flyer becomes "Broken Link"

"QR code printed on event flyer becomes error even if I access..." "I just remade my business card, but I was told that QR code cannot be read..."

These are troubles that often occur when you use QR code creation tool without knowing its mechanism well. Actually, there are two types of QR codes in the world: "QR code with expiration date" and "Indefinite QR code".

Important printed matter used in business. Once printed, collection is impossible. To avoid regret, let's learn correct knowledge and how to choose tools.

Which should I choose, "Static" or "Dynamic"?

There are roughly two types of QR codes.

1. Static QR Code

Convert input data (URL or text) as it is to QR code pattern. Jenee's tool is this type.

Merit: Since it does not go through server, it can be used semi-permanently. Once you make image, it continues to function even if tool disappears. Also, security risk is low.
Demerit: Link destination cannot be changed after creation (it will be reprinted). Also, if there is large amount of data, pattern becomes fine and difficult to read.

2. Dynamic QR Code

Mechanism to redirect to another URL via URL shortening service etc.

Merit: Link destination can be changed after distribution. Access analysis (how many people read) is possible.
Demerit: Since it goes through server of service provider, link becomes broken due to termination of contract or service stop. Free version often has restrictions such as "up to 30 days" or "up to 100 times". Also, advertisement may be displayed at redirect.

Conclusion: For business cards, pamphlets, documents to be stored for long time, you should definitely choose "Static QR Code".

Evolving QR Code (Micro QR / Frame QR)

QR code was developed by Denso Wave in 1994, but it continues to evolve even now.

Micro QR Code: Very small space-saving type. Used in narrow places such as board management of electronic parts. Feature is that there is only one cutout symbol (square mark).
Frame QR: Highly designed code where blank is provided in center of code and illustration or characters can be placed there.
iQR Code: New standard that can be printed on rectangular space.

Jenee's tool adopts standard "Model 2" which has highest compatibility and can be read by any smartphone.

Tips on Design to Improve Reading Accuracy

"Even though I made it, smartphone camera does not react..." Have you ever had such experience? Actually, QR code has rules that influence "Easy to read".

1. Keep Margin (Quiet Zone)

White margin is absolutely necessary around QR code. If you paint background color to edge or place characters emphasizing design, camera cannot recognize range of code. Let's secure margin of at least "4 cells (dots)".

2. Make Contrast Clear

"Background is light color, code is dark color" is iron rule.

〇: Black on white background, Navy on yellow background
×: White on black background (Inversion), Black on navy background, Pastel colors

Especially "Color Inversion (Negative Positive)" should be avoided because it becomes unreadable in many apps.

3. Proper Use of "Error Correction Level"

QR code has "Error Correction Function" that makes it readable even if there is dirt or damage. Level has 4 stages from L (7% recoverable) to H (30% recoverable).

Level L: Small amount of data and clean appearance. Ideal for small printed matter such as business cards.
Level H: When putting logo in middle or sticking on place where it is easy to get dirty (construction site etc.). Pattern becomes fine accordingly.

Among many tools, why is Jenee chosen by professionals? The reason lies in "High Basic Performance".
